To (1.1 'ui/wirt zit 11mg/ concern:

Be it known that l) RAY lll. MANsoN a eitizen of the United States, residing at Elyria, in the county of Lorain and Stato of Ohio, have invented certain newwmd useful Imprzwements in Telephone Desk-Stands, of which the following is a specification, reference being had therein to the accompanying; drawings.

My invention relates to telephone sets,

.and particularly toy what are known as desk sets. i

It has for its object the reduction of such an instrument which shall be of high elli-- oieney, simple and economical to manufacture, and not likely to get out of order, or if it dees which shall be easy to repair. In order to attain my object, l make my complete desk outfit in three parts.-viz., the receiver, connected ,to the stand through the usual oord, (and not illustrated because it forms no art of the present inventiorh') the desk-stan pro ierJ and the transmittor-sup-A port, which slides into the stand and carries the switch-hook parts except the springs. I mount the coil, switch-springs, and terminal rack in the base of the stand, preferably on a removable plate; but this manner of mounting specifically forms no part of the present invention, as such mounting may be either interchangeable or permanent without altering my invention.

My invention is illustrated in the aeeompanyingl drawings, in which- Figure 1 is a vertical sectional view of the desk stand and base with the transmitter and receiver removed. Fig. 2 is a similar View at right angles to Eig. l. Fig. 3 is a bottom view of the base with the mver-plate and mounting-plate rei'noved. Fig. 4 is a plan view from beneath the mounting-plate 1n the base.

In the drawings, A is the base, and A the, standard, of a deskset. The` switch mechanism of this set is partly contained in the base and partly in the standard. Meehanieal )ortions are all mounted in or on the standard, connected to and controlled by the revolver hook-lever D. contact-springs, however, the base, preferably plate.

ln the standard A', which is preferably sheathed with hard rubber or .similar mate- The electrical are arranged in on a separable basestrip a, secured at its upper end in any suiti able manner, as by screws or rivets, to the east head E. This head comprises a body iortion e, havingr a central passage-way e lor 'the passage of the transmitter-wires, a eailla11ge e2 litting the upper end of the tube a, and a laterally-bored cylindrical soeket-piece e3 for the knuckle,- joint of the transmitter. The cylindrical chamber formed in this Socket- )ieee (or bearing-head) communicates with the passage c, and the latter registers with an opening e* in the upper end of the vertieal support a, so that an uninterrupted channel for the wires is formed from the aforesaid Chamber to the inte-rior of the vertical standard. Into this chamber is fitted the hub e5, which has an annular channel ePz extending into it from one side, its lower wall being out away at e to pass the transn1itter-wires and suilieiently to allow play of the hub in its journal without compressinv the wires or cutting the insulation. On t is hub is mounted the stub plate or block el by means of a neck e, passing through an opening out in the upper part of the llange of the seeker-piece e3, the extent of this opening determining the anf ruler motion of the transmitter. The stubplate e? is bored out to form a centlal ebannel e, opening dirertly into the annuler chamber es. rThe traneniitter-wires 1G and 17 are led `through this channel into the chamber e", then wrap )ed in reverse directions around the centra spindle, then carried down through the channel e' and the opening e* into the hollow standard A.

Upon the vertical support a is pivoted at a, by means of a shoulder-screw or other wise, the vertical oseillatinr lever el, which at its upper end is fforked to take over a pin d on the lower arm d of the bell-crank hook lever D, and at its lower end is forked, as shown at a", to take over and operate the eireuit-ol1enging springs, to' which I will refer farther on. The support a, is provided with an upstanding lug, upon which is mounted a strong leaf-s )ring o2, whose upper or tree end bears upon t e arm d of the hooklever. In order to ive play to the latter, a slot e is eut in the l ange e2 of the cap E, and a similar registering slot eut in the upper end of the tube al.

At its lower end the support a is over- ICO turned and has Secured to'it by screws or rivets a button or disk al of insulating material, eut away at one side to permit the passage of theforked end a of the lever (L. Set in this disk are two contact-studs a?, which project through on the upper side of the disk behind the support a, as shown in Fig. 2, where they are connected, respectively, to the two transmitter-wires 16 17 The disk am may be of metal and the studs ai may be hushed therein with insulating material, and I also preferably provide a piece of sheet fiber or similar insulating material a, secured at its upper end under the nut a, of the pivotescrew a?, and its lower end turned under the end of the support a. This insulates the parts and prevents any aceidental grounding or crossing of the wires on the support..

The metal tube a" which forms my hollow standard is permanently secured at its lower end to the base A by means of the threaded ring alf and the nut a. The base of the stand is shown herein of pressed metal; but I may also make it a casting, preferably castironJ and when so made the nut (1, may be dispensed with, the base itself being threaded and screwing on the tube against the ring ai, Assuming such a base to b e employed, I mount therein to one side of the center, a terminal rack or strip carrying insulated terminals for the receiver, induction-coil, and switch-.e` irings. The switeh-springs are also mounte to one side, as shown 1n Fig. 4, wherein the terminahraek is lettered K and the springs S and s. The end of the spring S is covered with insulation, preferably by having a short strip of hard fiber turned about it and riveted fast, this insulated end lying in the fork a, as shown, when the parts are assembled. Mounted upon an insulating-bed tl and secured at one end lonly at t, is a )air of terminal-springs t t', wired to the coil and terminal-rack, and adapted, when the instrument is assembled, to be pressed down by the studs a7, therebyueonnecting the latter and the transmitter-wires into circuit with the coil and terminal-rack.

The parts shown in Fig. 4 may beV attached pcrmanentlyto the inside of the base, or their mounting may be on a separable plate (j secured within the base, the latter being shown in Fig. 3 exposed by the removal of all the parts. The idea of a separable mounting, however, I` do not claim specific.- ally as my invention nor any of the details thereof which I have show-n, any suitable form of mounting falling within the scope and purview of my invention.

The su port a, with the transmitter and the hookever parts upon it, slides bodily in and out of the tube a in the standard. In order to hold itv 'n place when inserted and yet render it ea 'ly removable,l have provided the spring-latch at, secured at its up per end to the support (L and having ils lower end a bent over, as shown. rl`his latchspring is punctured to receive the pin 19, and when it is desired to remove the vertical support and its parts from the standards A all that is necessary is to remove the cover plate in the base, which will shortly be described, and press back the spring dfwhose end al will then be exposed. Un replacing the vertical parts in the tubi` thc springlatch will of itself rengage thc pin a", locking the parts in position. The base of this instrument may be formed as' follows: A pressmetal shell al is shouldered around a central opening to fit upon the tube a.12 and lie against the screw-ring d'5, which is threaded thereon. Inside the shell am is fitted a pressmetal liner having a peculiar configuration, for purposes which l will now point out, The liner has its upper part shaped in at I/ to form a tubular neck fitting snugly around the tube am, and with the upper end of its flange or tube pressing against the inside edge of the shoulder or shell e". It is necessary for certain reasons that the liner B should not turn upon the tube. To secure this, a projection b2 is punched in from one side of the neck b', and in one side of the tube am a slot or keyway is formed, as shown at (L17, in which the projection b may lie when the liner is slipped on a tube. The liner is held in place by meansfof a threaded. nut a, which is set up against it on the tube.

At the lower and outer edges of its bell the liner B has a horizontal flange and two vertical flanges, (lettered b, b, and b, respectively.) The horizontal flange b stiffens the whole base perfectly'. The vertical flange B incidentally stifens the top of the base all around, and the flange bl forms one side of a channel to receive the rubber or leather ring lf, which serves to form a soft pad or deadencr for the base of the set. The inner side of this ring-- channel is form ed by the flange-ring b, whose horizontal flange b is notched at bl2 at intervals. Against the lower face of this ring rests the cover-plate B, provided with loekl IOO IIC

ing-teeth or radial projeetionsbi to register i with and take into the notches b, so that by inserting the same and then slightly turning the 'cover-plate the projections b1 will pass under the flange Il and loek the plate in position.

My invention. set forth herein does not relate to any of the parts in the base of the desk set as such, nor does it depend upon any special arrangement of those parts. It has to do particu arly with the parts in the standard, and while I have described and illustrated herein a convenient type of base and fittings therefor I do not by any means wish to limit myself thereto,nor, eonversely,
